Description

Under rare conditions, the effective permissions of an object might be incorrectly calculated if the object has a specific configuration of metadata-driven permissions in M-Files Server versions 23.9, 23.10, and 23.11 before 23.11.13168.7, potentially enabling unauthorized access to the object.
